Director Stephen Gaghan's gripping new film "Syriana" explores the roots of 21st century civilization's biggest dilemma: Peak Oil. Inexpensive fossil fuels - oil and natural gas - have floated both the corporate-controlled global economy and U.S. imperial planetary hegemony for the past several decades. Now, the party is over, as "elephant" fields like Kuwait's Burgan are peaking, oil companies are maintaining sagging portfolios by buying up other companies' reserves (real and fictitious). The world is beginning to grasp the significance of living without immediate and inexpensive access to one of the 20th century's most vital resources.
